Harris was taken into custody earlier this month after the deadly encounter at a QuikTrip convenience store in Phoenix involving his 16-year-old daughter.

The 40-year-old was waiting in the parking lot to pick up his daughter and two friends when Armstrong approached him asking for money. Harris gave him some change and Armstrong went into the store.

Harris’ daughter came out of the store and told her father that a man tried to enter her bathroom stall by violently shaking the door, police said. She said she told the employees who alerted the security guard.

She then identified Armstrong as the alleged harasser when she spotted him walking out of the store.

Possibly thinking not enough was being done, Harris approached the security guard and told him to “take care of the situation, or he would do it himself.” The guard said the incident was being handled.

The protective father, however, confronted Armstrong about the incident and then attacked him, authorities said.
